Electrocardiogram signal denoising using non‐local wavelet transform domain filtering

Abstract: Electrocardiogram (ECG) signals are usually corrupted by baseline wander, power-line interference, muscle noise etc. Numerous methods have been proposed to remove these noises. However, in case of wireless recording of the ECG signal it gets corrupted by the additive white Gaussian noise (AWGN). For the correct diagnosis, removal of AWGN from ECG signals becomes necessary as it affects the diagnostic features. The natural signals exhibit correlation among their samples and this property has been exploited in v… Show more

“…In the paper the on-line tuning quantity σ of the PF with the measurement noise variance with the help of the wavelet transform is designed. The measured stream y ω pkq could be approximated by a low-order polynomial or a piecewise low-order polynomial in an observation interval [25]. This interval size is corresponding to sampling number.…”
